One of the displays that has generated a lot of buzz at the Paris Airshow 2011
is EADS’ ZEHST
concept – a zero-emission hypersonic airliner, that could be whisking passengers from Tokyo to London in under 2.5 hours, by the year 2050. Sitting alongside the ZEHST model, however, is another EADS concept aimed at the more immediate future. It’s called VoltAir, and it’s a proposed all-electric airliner that could be flying within 25 years.
EADS has used the opening day of the 2011 Paris Airshow
to showcase an aircraft of the future concept which contemplates speeds beyond Mach 4, meaning it could make the run from Tokyo to London in under 2.5 hours. The ZEHST (Zero Emission Hypersonic Transport) study incorporates three different propulsion systems and could carry passengers to heights of 100,000 feet (32 km) while still meeting the projected European Commission targets for reduced noise, CO2 and NOX emissions by 2050. Blue sky indeed!
Because structural integrity is so crucial to the safe operation of aircraft, their bodies are regularly inspected for signs of faults such as stress fractures. Some of these fractures can be virtually invisible to the human eye, so scientists are looking into the use of permanently-installed sensors, that would continuously provide information on the state of various parts of the aircraft. Given that one commercial airliner could potentially utilize hundreds of these sensors, however, running wiring to all of them could get quite complex. Using battery-operated sensors is one option, although ground crews would be constantly checking and changing batteries, plus it would be wasteful. Researchers from EADS Germany and the Vienna Institute of Technology now think they might have a better alternative – self-powered sensors that wirelessly transmit data.
Hydrogen has great potential as a clean fuel source for powering our cars
, but it also poses some big hurdles – in particular, how to store it. Making practical use of hydrogen in gas or liquid form raises difficulties in terms of volume and pressurization – a hydrogen gas tank for a car would need to be around four times larger than current petroleum tanks. Another possible solution is the use of solid state hydrogen and the European Aeronautic Defense and Space Company (EADS), along with the University of Glasgow, hope to boost this approach by developing a new storage system using materials modified at the nanoscale that receive and release the hydrogen at a faster rate.
Engineers from the Bristol wing of the European Aeronautic Defence and Space Company (EADS)
have announced the development of the first bicycle using Additive Layer Manufacturing (ALM) technology. The manufacturing process involves "growing" the components from a fine nylon powder, similar in concept to 3D printing
. Said to be as strong as steel, the end product is claimed to contain only a fraction of the source material used by traditional machining, and the process results in much less waste. It also has the potential to take manufacture to precisely where the component or product is needed, instead of being confined to factories often located a great distance away.
When Gizmag paid a visit to the Paris Green Air Show
in June, there was one craft on display that seemed to steal the show. The Green Cri aerobatic electric airplane hadn't even left terra firma, yet was surrounded by eager onlookers for much of the time it was there. Now the four-engined prototype has returned to Le Bourget airfield for its maiden flight in the sunny skies above Paris.
October 8, 2005 EADS and DRS Technologies have agreed to collaborate on U.S. marketing and production of the EADS HELLAS laser-based obstacle warning system that offers unprecedented protection for helicopters against difficult-to-detect obstacles, such as power lines. This agreement covers the EADS Defence Electronics’ HELLAS-W (Warning) obstacle warning system, which already is in operation on Federal German Police helicopters, and the new HELLAS-A (Awareness) obstacle warning system, which is in development for German Forces NH90 helicopters and has been identified for potential use with U.S. military forces.
